Left 4 Dead 2

I currently have some custom maps and custom weapons installed from steam workshop, this has been happening for a while now and its really annoying, basically when i run custom maps, it loads for a while, then says somethings lacking consistency or something, and then says something like model/boomette or model/spitter or model/gnome, i currenly have no mods that changes textures of infected but i do have mods that change weapon skins and sounds and custom maps, thank you very much! :)

Consistency errors that aren't the map are a problem with the server; they shouldn't be enforcing consistency. If a friend is hosting, have them enter sv_consistency 0 in the console while in lobby. A few add-on campaigns have custom infected and other models, so even if you don't have a mod for that specific thing it might be from a map.
